Occupying California's ports may harm the "99%;" Capital Public Radio's Pauline Bartolone discusses California's latest health issues; Chinook Salmon numbers are burgeoning after years of near extinction; Making skyscrapers safer in earthquakes.

Occupy California's Ports Occupy protestors
are planning to shut down California's ports on Monday, December 12
to "disrupt the profits of the 1%." We'll speak with an
occupy protester at the port of Oakland and Michael Shaw, from the
California Trucking Association, who says the protests will harm
middle-class workers in the shipping industry, not the "1%."

Return of the Chinook Decades of altering the
Sacramento region's waterways nearly wiped out the area's Chinook
salmon run. Kevin Shaffer, a Department of Fish and Game
manager who works closely with the Nimbus Fish Hatchery, tells us
how human intervention has brought the Chinoook salmon's numbers
back. Capital Public Radio's multi-media producer, Andrew
Nixon, also joins the discussion to talk about a video he made of
salmon spawning at the Nimbus Fish Hatchery this season.

Skyscrapers and Earthquakes UC Davis
engineers will soon study how the steel columns that secure
skyscrapers to their foundations stand up during earthquakes,
possibly making the towering structures safer and cheaper to build.
David Grilli, the lead doctoral student working on the project,
joins us.
